Hi Fiona,
I so hear you on the fat thing - i have been on weight watchers online a bit and since they calculate points based on kilojoules and sat fat things like nuts have huge points! I guess what i'm thinking is that david's research stcks up and there's so much of it, we might as well give this a red hot go :)
I mean, I'm pretty over having to watch points so I don't grow out of my clothes and really love the idea of the body being able to tell us when it's nourished. How wonderful if all that's stopping that is our sugar habit!! I'm not a huge consumer of sugar and I'm on my first week, though I'm still having a sugar hit or so a day as I slowly eat what's left of it in the house, though I'm sure that's a dumb idea that's going to streeeeetch my withdrawal for a while.
I eat a half weet bix and some all bran (that once I am done with the pack I'll buy another as it's got 13% sugar - will go for a less sugar one). I have that with a half cup of light soy milk, which I'll try to swap for rice milk when this carton is over. For lunch I have veggie stews from my slow cooker, of poached fish in tomato sauce. If I'm hungry at work I'll snack on a carrot, apple, mandarin - basically fruit or veg. For dinner I'll have something similar to lunch - a light curry, or steamed fish, maybe some pasta. If I crave dessert I mash a banana onto a plate, sprinkle a cake of weetbix on top, pour in a teeny bit of milk just to dampen the weekbit then microwave for a minute. I dust some cinnamon over it and it tastes really sweet - somehow bananas seem sweeter when warm (or at least I think so...). While some of my friends think that's a stomach-churningly awful-sounding dessert, I love it as a guilt-free treat :)
Hope this helps, stick to it and let us know how you go - I've just started like you so good to have someone on the same step.
